Predicted to enable 1-alkyl-2-acetylglycerophosphocholine esterase activity; platelet-activating factor acetyltransferase activity; and protein dimerization activity. Acts upstream of or within spermatogenesis. Located in cytoplasm. Is expressed in several structures, including alimentary system; eye; genitourinary system; hemolymphoid system gland; and nervous system. Orthologous to human PAFAH1B3 (platelet activating factor acetylhydrolase 1b catalytic subunit 3). [provided by Alliance of Genome Resources, Apr 2022]
